Description

[0001] The present invention relates to a method for vehicle-to-vehicle communication. The present invention further relates to a corresponding device, a corresponding computer program, and a corresponding storage medium. State of the art

[0002] In the field of vehicle-to-vehicle communication, it is already known to network vehicles wirelessly or via Dedicated Short Range Communication (DSLC) to exchange safety-relevant data, such as warnings of accidents or hazards on the road. Systems like "Porsche Connect" and the "Porsche2X" function primarily offer navigation services, hazard warnings, and function controls. However, communication between vehicles of the same brand is primarily focused on safety-related or vehicle-related aspects. The exchange of information that goes beyond pure safety, such as details about the engine, routes traveled, vehicle equipment, personal preferences, events attended, or memberships in brand clubs, is not currently supported. Disclosure of the invention

[0003] One problem is that drivers of sporty vehicles of a particular brand often show interest in the specifications and features of other brands' vehicles, but lack a direct, easy way to exchange this information between vehicles. This information gap prevents personal exchange between drivers, even though both are part of a community of technically minded car enthusiasts.

[0004] The described problem is solved, according to the independent claims, by providing a method in which a vehicle recognizes nearby similar vehicles, receives their previously released information via a V2V interface, and displays it on suitable screens such as a center console or a head-up display. The owner of each vehicle can determine which information, such as engine details, model name, routes driven, photos, or personal data, they wish to disclose.

[0005] This approach offers the advantage that drivers of vehicles of the same brand, when in close proximity, gain immediate access to interesting, shared information. This strengthens the sense of community, expands the exchange of information, and creates a new form of interaction that goes beyond mere safety considerations. Since the owner determines which data is shared, privacy is protected.

[0006] Further advantageous embodiments of the invention are specified in the dependent claims. For example, individual pieces of information can be displayed using augmented reality by optically superimposing them around the other vehicle located in front of the user's own vehicle. The retention of received information after the vehicles have separated can also be configured to allow long-term access to this data. Brief description of the drawings

[0007] Fig. Figure 1 shows a schematic representation of the procedure when a vehicle is nearby (left) and directly ahead (right). On the left, another vehicle is displayed on a center console screen, for example, as a rotatable and zoomable 3D model with associated, authorized information. On the right, it is illustrated how, when another vehicle is in front of the driver's vehicle, certain basic information is displayed in a head-up display using augmented reality. Embodiments of the invention

[0008] One embodiment will now be explained with reference to the drawing. If another vehicle of the same make is within the detection range of the V2V communication interface, the driver's vehicle receives a message that appears on the center console display. This message indicates that shared information is available. If the driver acknowledges the message, a virtual, freely movable model of the other vehicle appears on the center console, supplemented with data authorized by the respective owner. This can include basic technical data such as model name or engine specifications, as well as specific route segments marked by the driver of the other vehicle, reflecting their preferences and driving style. Photos, similar to a digital business card, personal contact information, details of club or other organization memberships, or data on recent trips can also be displayed.

[0009] If the detected vehicle is directly in front of your own vehicle, certain information is additionally displayed in the head-up display. There, information such as the model name, mileage, or other key data can be visually positioned around the vehicle actually visible using augmented reality. This display is particularly intuitive, as the driver perceives the information in direct context with the vehicle ahead. Once the vehicles move apart again, the connection is broken. Depending on the settings, however, the received information can remain visible on your own display, for example, to be viewed later at a convenient time.

[0010] The function is specifically designed for stationary situations, such as at traffic lights, level crossings, or intersections, as there is time to calmly review this data. The invention thus creates a new form of contact and information exchange between drivers of vehicles of the same brand, going beyond existing safety-focused forms of communication and enabling enriching interaction oriented towards personal interests.
